SKIPPER MECHANISM FOR LOOl'i/IS.

Application filed June 15, 1922.

To all whom it may concern:

Be it known that I, SrMnoN S. JACKSON,

a subject of Great Britain, residing at Hyde Park, Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Shipper Mechanism for Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to the devices which are employed in looms for the purpose of shipping the driving power on, and unshipping the driving power, as well as controlling the action of the'brakes. It has relation to the rockshafts which in the case of some looms extend across the front of a loom from one side of the latter to the other side thereof, and by means of which shipper and brake mechanisms located at one side are cont-rolled by stop-motion connections, the lattersometimes located at the opposite side of the loom. The invention provides a new and improved shipper-mechanism controlling rockshaft which, in addition to securing 5 other advantageous resultsgives the weaver greater control of the loom. The invention has been designed more especially for use in looms of the high or elevated take-up roll type, but is not restricted to use in that type alone of looms.

The accompanying drawings show an illustrative embodiment of my invention, in which,-

Fig. 1 is a plan view of certain parts at the forward end of a. loom, including the said illustrative embodiment of my invention, but with the shield for the take up roll omitted.

Fig. 2 is a front view of the same, showing the said shield.

Fig. 3 is a side elevation of the parts at the left-hand side of Figs. 1 and 2.

Having reference to the drawings As heretofore in the art, the high take-up roll 1 is journaled in elevated bearings in connection with the forward portion of the loom-frame, it being solocated that the cloth 00 passes to the upper portion of its periphery directly from the fell, and thence to the cloth-roll 2 upon which it is wound, said cloth-roll 2 being driven by peripheral contact with the take-up roll 1. At 21, 21, are the upwardly-pressed slides engaging with the ournals 22, 22, of the cloth-r01 Serial No. 568,512.

and serving to keep the periphery of the cloth-roll pressed against that of the takeup roll as in Fig. 3. At 4, Figs. 2 and 3, is shown the shield for the take-up roll, such shield being omitted from Fig. 1. The ship per-handle 5 is as usual mounted at the left side of the loom upon the pivot 6 projecting from the loom-side 7; it is coupled in wellknown manner by its projecting pin 51 to the slotted upper end of the link 8 extending to the clutch and brake mechanism (not shown), and is provided at its lower end with the usual hooked portion 59 for engaging the brake-lever after the said lever has been lifted by the weaver and holding it to keep the brake free and allow the loom to be turned over by hand. In the forward position occupied by shipper-handle 5 in the drawings its pin 51 supports link 8 in a relatively elevated position, with the brake ofl' and the driving power on, as during the running of the loom. At the right-hand side of the loom are the connections through which the warp-stop-motion mechanism (not shown) effects the unshipping, etc., of the loom, such connections being represented by the link 9 through which the warp-stop mechanism operates to knock off the shipperhandle when such mechanism detects breakage of a warp-thread.

My invention comprises a new and improved form of shipping rock-shaft 10, mounted in elevated bearings at the front of the loom extending across the loom from side to side, and which is actuated by the link 9, to trip the shipper-handle 5 in order to stop the loom when breakage of a warp-thread occurs. Heretofore, the rockshaft employed has usually been a straight shaft, and has had no other utility than its elemental one of tripping the shipperhandle or other shipper devices under the control of the warp-stop-motion means.

In accordance with my invention I form the rockshaft 10 with a forwardly cranked or ofiset intermediate portion exceeding the full length of the cloth-roll 2. This form allows it to extend across the loom with its said intermediate portion forward of the said rolls 1 and 2, and clearing the full clothroll, and at the same time permits its bearings to be located as shown in or in connecnection with the loom sides 7, 7, in relatively rearward positions in line with points within the diameter of a partly-filled clothroll That is to say, the form referred to enables the said bearings to be located at a distance from the axis of the cloth-roll which is less than the radius of the cloth-roll at a comparatively early stage in the Winding of said roll. Thus by my invention I avoid projection of the bearings of the said rockshaft at the front of the loom into the space Where the weaver stands and passes back and forth. i 1

The cranking of the intermediate portion of the rockshaft 1O enablestheweaver to rock the said roclzshaft from'any point at which he may be standing across the front of the loom, and through such rocking actuate the shipper devices to throw the driving power on and off, to start and stop the loom. This rendersit unnecessary for him to step to the side of thelooni at which the shipperhandle is located. In the present instance I employ as coupling means between tl'ie rockshaft 10 and the shipper-handle 5 the arm 12 fixed upon one end of the rockshaft 10 out side of the loom-frame, and the link 13 connecting'the end of said arm12 with the pro ing rod. 7 i

jecting pin 51 upon the shipper-handle 5.

The link 9 from the warp-stop lll'lBOllZr nism is attached to an arm 91 fixedupon the right-hand end of the said shipper-actuat- Of great value and convenience is the utis lization of the rock-shaft 10 as a shipperactuating means, it affording the weaver more perfect control of the loom. The great importance of enabling the weaver to stop the loom instantly from any point in. front thereof at whiclrhe may be standing .will be realized. 1 i v What is claimed as the invention is,. 1; In a loom, the combination witha high take-up roll, a cloth-roll driven by frictional Contact with said take-up roll, and a ship per-handle at one side oftherloom, of a.roclr--- shaft exteiidin "across the front of the loom-i frame, operatively connected with theshi per-handle, and having a'cranked. interme= diate portion exceeding thev length of the wound roll of cloth, adapted to clear said roll, and by means of which the said rocl-:- shaft may be rocked manually from any point in front of the loom to move the shipper-handle to start or stop 'theloom'.

2. In a 100m,' in combination, shipperhandle, a rockshaft extending across the front of the loom, directly connected with said shipper-handle, and having an elongated crankedintermediate portion accessible to the weaver across the front of the loom by means of which the roclrshaft may be rocked by the weaver flOlIl'fil point in the width of the loom to actuate'the shipper: handle to start and stop the :looin.

3. In aloom; in combination, shipperhandle at one side ofthe loom warp-stopmotion connections at the other side thereof, and arockshaft directly connectedv at one end with said shipper-handle and at the other with said warp-stop-motion connec tions and having cranked intermediate portion accessible-to the. weaveracross the frontof the loom, by" cans of which the weaver while standing infront of .theloom may manually rock the. said .rockshaft to throw said shippenhandle to start and stop the loom. Y 7

Ina loom, per-handle..at one side ofythe loom, clothe, roll, and bearings adjacent the opposite ends of the said. cloth-roll located, at a, distance from the axis of the cloth-roll which is less. than the radius of the wound mass at an in; termediate stage in the, winding-up of the cloth, of a ,roekshaft mounted in the said bearings,- operatively connected with the shipper-handle,.and having a cranked intermediateportionexceedingthe length of the Wound roll ofcloth, adapted to clear said roll, and which may be grasped by the weaver at anyipoint across the front ofthe loom rock the rockshaft manually to move the shipper-handle to start or stop the loom.

In testimony whereof I allix my signature in presence of twowitne'sses.
